When we practice Yoga each day, we gain mastery of/over the most important thing that we really have (or need to have) control of in our lives; we gain control of our self (in the form of the ego-body-mind).
And with this control, we can then gradually eliminate all false self-expressions from our being, such as the expression of the conditioned self, the wounded self, the self in the context of society, and so forth, and get back to the essence of our True, eternal, unchanging, Self within the context of existence itself as an expression of the divine spark that illuminates our, and all of, life.
Practicing Yoga, therefore, is essentially about making space within our bodies and minds for our highest and truest expression to shine through.
It is about embodying this highest expression often enough that it becomes our default expression, coloring and shaping our overall lived experience.
Always remember that the more that you let go of your false self expressions, the more fully you will come into your higher expression and more fully back to Love. This will give you more freedom and control in your life to create less suffering and to generate more joy.
